JOURNAL-COOLING DEVICE.

To all whom it may concern:

Be it known that I, WILLIAM H. OLING- MAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Journal Cooling Devices, of which the following is a specification.

This invention relates to improvements in journal cooling devices particularly adapted, though not necessarily limited in its use, to cooling car axles.

Heretofore in devices of this character there has been employed a tank for holding a supply of cooling liquid and this tank has usually been supported by the car truck and located some distance from the journal; the cooling liquid being conducted from the tank by means of a flexible pipe to be dis charged upon the journal. With this structure considerable difficulty and inconvenience has been experienced in that the liquid in the pipe as well as that in the tank freezes. To overcome these ditliculties and objections and to provide an improved device of this class having means whereby the tank may be supported in close proximity to the journal whereby the heat from the heated journal may be utilized to prevent the water in the tank from freezing, is one of the obj ects of the present invention.

A further object is to provide an improved device of this class having means for freely supporting the tank from the car body and also means for supporting the tank by the journal box whereby the water in the tank will be subjected to constant agitation when the car is moving.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing, exemplifying the invention, and in which Figure 1 is a vertical sectional view of an improved device of this character constructed in accordance with the principles of this invention and showing a journal box in section. Fig. 2 is a front elevation of Fig. 1. Fig. 3 is a sectional view on line 33, Fig. 1. Fig. 4 is an enlarged detail sectional view of a portion of the screen and guide therefor.

Specification of Letters Patent.

Application filed April 28, 1911.

Serial No. 623,443.

Referring more particularly to the drawmg, the numeral 5 designates a tank which may be constructed of any suitable material and may be of any desired size and configuration. This tank is provided with a closure 6 and is adapted to be flexibly suspended from the car sill 7 by means of a suspension device 8 in the form of a hook or the like with which hook the flexible members or chains 9 have detachable engagement. The tank is provided on opposite sides with supporting hooks 10 with which the flexible members 9 also have engagement and the flexible members are of such a length that the tank 5 may be raised or lowered by adjusting the flexible members with respect to the hooks 10.

Projecting from one face of the tank is a chamber 11 which is of a size somewhat less than the width and the height of the tank 5 so that when the tank 5 is supported in position by means of the flexible members, the chamber 11 will project into the opening 12 of the journal box 13. The journal box 13 here shown is of the standard type and projecting below the bottom 14: of the tank, preferably from that portion of the bottom beneath the chamber 11 are spaced flanges or projections 16 which engage over the edge of the opening of the journal box, as shown in Fig. 1. A nozzle 17, preferably in the form of a stop cock having a valve 18 is connected with the chamber 11 and has communicationwith the interior thereof. This cook or nozzle 17 is of such a length that it will stand in close proximity to the end of the axle 19 when the tank 5 is placed in position, and when the valve 18 of the cock is open the cooling fluid will pass out of the cock or nozzle 17 to be discharged against the axle 19.

The housing 11 is preferably ofl'set so as to project beyond the wall of the tank and a screen 20 formed of any suitable reticulated material is provided which moves in guides 21 and forms a partition between the chamber 11 and the main portion of the tank 5. This screen serves as a means whereby foreign matters may be prevented from entering the housing 11 and which would clog the cook or nozzle 17.

With this improved construction it will be manifest that inasmuch as the housing 11 engages and rests upon the edge of the opening of the journal box 13, a comparatively large body of Water will be held in Patented Dec. 30, 1913.

close proximity to the heated journal, so that the heat of the journal will serve as a means for preventing the water in the housing 11 from freezing. Furthermore, the heat radiated by the journal box will also be conducted to the bottom of the tank by means of the engagement of the bottom of the journal box and this heat will also serve as a means for preventing the water in both the housing II and the tank 5 from freezing.

The tank may be raised or lowered by means of the adjustable connection of the tank with the flexible members 9. By the provision of these flexible members 9 the tank will also be flexibly suspended from the car body so that during the motion of the car, a swinging movement will be imparted to the tank 5 and this will impart agitation to the cooling fluid in the tank.

Obviously the tank may be replenished through the closure 6 and when it is not desired to use this device it may be readily removed by detaching the flexible members from the suspension device 8.

Obviously this improvement may be read ily attached to any car without altering the structure of any of the parts.

What I claim as new, is:

1. In a journal cooling device, the combination of a journal box having an opening thereinto, a journal, a liquid tank, said tank being provided with a reduced portion detachably engaging the edge of the journal box opening, means for holding said portion in posit-ion with respect to the opening, means for supporting the tank, a liquid discharge outlet leading from the reduced portion of the tank in close proximity to the journal, and a screen in the tank extending across the said reduced portion.

2. The combination of a journal box having an opening thereinto, a journal, a cooling device disposed in proximity thereto and embodying a tank provided with a reduced portion forming a chamber adapted to project into the opening of the journal box, a screen dividing the body of the tank and the chamber, a flexible support for the tank,

said chamber engaging the edge of the journal box opening, there being spaced projections carried by the tank between which the edge of the journal box opening extends, and a .stop cock leading from the chamber adjacent the journal and projecting into the journal box opening.

8. In a journal cooling device, the combination of a journal box having an opening thereinto, a journal, a liquid tank, said tank being provided with a reduced portion detachably engaging the edge of the journal box opening, means for holding said portion in position with respect to the opening, means for supporting the tank, a liquid discharge outlet leading from the reduced portion of the tank in close proximity to the journal, and a screen in the tank between the inlet and the outlet thereof.

l. In a journal cooling device, the combination of a journal box having an openingthereinto, a journal, a liquid tank, said tank being provided with a reduced portion engaging the edge of the journal box opening, means for holding said portion removably in position with respect to the opening, means for supporting the tank, a liquid discharge outlet leading from the reduced portion of the tank in close proximity to the journal, and a removable screen in the tank between the inlet and the outlet thereof.

5. The combination of a journal box having an opening thereinto, a journal, a cooling device in proximity thereto and embodying a tank having a reduced portion forming a chamber adapted to project into the opening of the journal box, a stop cock leading from the chamber adjacent the j ournal, means within the tank for straining liquid before its outward passage through the stop cock, a flexible support for the tank, and an appliance operatively related to the tank and journal box for removably connecting the tank and the journal box.

6. The combination of a journal, a journal box therefor having an opening, a liquid tank removably secured to the journal box and having its body portion protruding therewithin to a point adjacent the journal, and an appliance entirely within the journal box and secured to the inwardly pro-' truding portion of the body of the tank for directing liquid from the tank against the journal.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 24th day of April A. D. 1911.
